Gold line icons for agricultural monitoring

A clean, minimalist 3x3 grid of thin-line icons rendered in a polished gold finish against a stark black background. These icons represent agricultural or scientific monitoring concepts, including a bovine silhouette, livestock identification, biological structures, texture analysis, temperature measurement, hydration or moisture levels, steam or heat emission, global logistics or environment, and quality certification . The aesthetic is modern and sophisticated, often used in professional dashboard designs, agricultural technology interfaces, or sustainable farming branding. The lines are uniform in weight and spacing, creating a balanced and orderly composition that is highly legible. The deep black background enhances the metallic gold color, giving the icons a premium, high-tech appearance suitable for corporate or industrial presentations.
